摘 要
真空烹饪技术作为一种新兴的食品加工方式,近年来受到广泛关注。本研究旨在探讨真空烹饪对食材营养成分的影响,以期为优化食品加工工艺提供科学依据。研究选取了多种常见食材,包括肉类、蔬菜和谷物,通过对比传统烹饪方法与真空烹饪条件下营养成分的变化,分析其在维生素保留率、抗氧化活性以及蛋白质结构稳定性等方面的差异。实验采用高效液相色谱法、紫外可见光谱法及质构分析等现代分析手段,系统评估了不同温度和时间参数下真空烹饪对食材营养特性的具体作用机制。结果表明,真空烹饪能够显著减少热敏性营养物质的损失,尤其是在维生素C和类胡萝卜素的保留方面表现出明显优势。此外,该技术有效抑制了氧化反应的发生,从而提高了食材的抗氧化能力,并在一定程度上维持了蛋白质的天然构象。本研究的创新点在于首次揭示了真空环境对食材内部化学反应路径的调控作用,并提出了基于营养保护的最优真空烹饪参数范围。这一发现不仅深化了对真空烹饪技术的认识,还为开发更健康的食品加工方案提供了重要参考,具有重要的理论价值和实际应用意义。

Vacuum cooking technology, as an emerging food processing method, has garnered significant attention in recent years. This study aims to investigate the impact of vacuum cooking on the nutritional components of food ingredients, providing scientific evidence for optimizing food processing technologies. A variety of common ingredients, including meat, vegetables, and grains, were selected for analysis. By comparing changes in nutritional components under traditional cooking methods versus vacuum cooking conditions, differences in vitamin retention rates, antioxidant activity, and protein structural stability were evaluated. Modern analytical techniques such as high-performance liquid chromatography, ultraviolet-visible spectroscopy, and texture analysis were employed to systematically assess the specific mechanisms by which vacuum cooking affects the nutritional properties of ingredients under varying temperature and time parameters. The results indicate that vacuum cooking significantly reduces the loss of heat-sensitive nutrients, demonstrating a clear advantage in the retention of vitamin C and carotenoids. Additionally, this technology effectively suppresses oxidation reactions, thereby enhancing the antioxidant capacity of the ingredients and partially preserving the natural conformation of proteins. The novelty of this study lies in its first revelation of the regulatory effects of vacuum environments on internal chemical reaction pathways within food ingredients, along with the proposal of an optimal parameter range for vacuum cooking based on nutritional preservation. This discovery not only deepens the understanding of vacuum cooking technology but also provides crucial references for developing healthier food processing solutions, holding important theoretical significance and practical application value.
